5.1 Entering Values
When applicable, values can be changed by either displaying the current value, then using the arrow keys, or from
a computer connected to the pump. The new value will be stored in the pump’s non-volatile memory, meaning that
the new value will not be lost the next time that power is applied to the pump. The only exception is when the
pumping rate is changed from an attached computer while the Pumping Program is operating. In this case the new
pumping rate will not be stored in non-volatile memory.
A displayed value can be changed by pressing the arrow keys below each digit. If the value to be changed is not
currently displayed, when applicable, momentarily press the key associated with the required value. The display
will show the setting’s current value and its units, if any.
While the current value is being changed, the units LEDs associated with the value, if any, will blink. Except
where noted, the new value is stored, and/or the selected operation takes effect, when either
1) A non-arrow key is pressed or
2) After a 2 second delay since the last arrow key was pressed.
If the new value is valid and different from the original value, the display will blink, indicating that the new value
was stored. Otherwise, if the value was invalid, an error message will be displayed. Pressing any key clears the
error message and restores the original value.
In general, if a parameter has 2 values, ‘off’ and ‘on’, they are represented by the numbers ‘0’ and ‘1’, respectfully.
5.2 LCD Display
The display consists of a 4 digit reflective LCD (Liquid Crystal Diode) display. This is the general purpose user
display device for displaying numerical data, functions and parameters. The colon (:) is used for displaying time or
for separating function abbreviations from their parameter values. In the upper left corner is a triangle that
indicates valid reception of RS-232 remote communications.
5.3 LEDs
To the right of the LCD are 8 red, round, LED (Light Emitting Diode) indicators. The first 2 columns display the
units of the displayed values. Units are expressed using 1 or 2 LEDs. For instance, ‘mL / hr’ is expressed by
lighting the ‘mL’ and the ‘hr’ LEDs.
‘Dispensed’ indicates that the displayed volume is the total ‘Volume Dispensed’ or pumped.
When ‘Pumping’ is lit (not blinking), the motor is operating, either infusing or withdrawing. If blinking, the motor
is not operating, and the Pumping Program is paused. When the pump is restarted, the Pumping Program will
resume at the point where the Pumping Program was interrupted. When not lit (not blinking) the pump is stopped,
but the Pumping Program may be operating a pause Phase. Starting the pump, when the Pumping Program is
stopped, will start the Pumping Program from the beginning (Phase 1).
‘Withdraw’ indicates that the pumping direction is set for withdrawing. If not lit, then the pumping direction is set
for infusing. When blinking, “Sticky Direction” is set. Also, the ‘Withdraw’ LED indicates that the “Volume
Dispensed” refers to the volume withdrawn. If not lit, the “Volume
Dispensed” refers to the volume infused.
